  2. Xanthochromia - Wikipedia

    en.wikipedia.org/wiki/Xanthochromia

    Xanthochromia, from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "colour", is the yellowish appearance of cerebrospinal fluid that occurs several hours after bleeding into the subarachnoid space caused by certain medical conditions, most commonly subarachnoid hemorrhage. [1]

  3. Froin's syndrome - Wikipedia

    en.wikipedia.org/wiki/Froin's_syndrome

    Froin's syndrome – coexistence of xanthochromia, high protein level and marked coagulation of cerebrospinal fluid (CSF). It is caused by meningeal irritation (e.g. during spinal meningitis) and CSF flow blockage by tumour mass or abscess. [1]

  4. Cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid

    Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid ...

  5. Configuration state function - Wikipedia

    en.wikipedia.org/wiki/Configuration_state_function

    In quantum chemistry, a configuration state function (CSF), is a symmetry-adapted linear combination of Slater determinants. A CSF must not be confused with a configuration . In general, one configuration gives rise to several CSFs; all have the same total quantum numbers for spin and spatial parts but differ in their intermediate couplings.

  6. Glossary of physics - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_physics

    A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.

  7. Cerebrospinal fluid flow MRI - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_Fluid_Flow_MRI

    Cerebrospinal fluid (CSF) flow MRI is used to assess pulsatile CSF flow both qualitatively and quantitatively. Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [ 1 ]

    velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian heat capacity ratio: unitless surface tension: newton per meter (N/m) delta: change in a variable (e.g. ) unitless Laplace operator: per square meter (m −2)

  9. Cerebrospinal fluid leak - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_leak

    A spontaneous spinal CSF leak refers to any CSF leak that has not been preceded by a surgical or other medical procedure. [ 12 ] [ 29 ] [ 37 ] Later evidence suggests that these leaks result from either a discogenic pathology, such as microspur, osteophyte or spinal disc herniation that pierces the dura like a knife, connective tissue disorder ...
